Summit X450e-48p Power Supplies

The Summit X450e-48p switch is powered by both an internal power supply and an optional external
redundant power supply system.
Internal Power Supply. The internal Summit X450e-48p power supply can provide 370 W of PoE power,
as follows:
In a 24 port configuration, it provides 15.4 W to each port.
●
In 48-port configuration or any combination of ports where total PoE power does not exceed 370
●
watts, it provides 7.7 W to each port.
If the total system demands exceed this power limit, you can specify:
Port priorities to identify which ports should be ranked higher when allocating power.
●
Port disconnect precedence to specify the method of shutting off ports when not enough PoE power
●
is available.
NOTE
For a detailed discussion of these concepts, see the Power over Ethernet section in the ExtremeXOS Concepts
Guide.
External Power Supplies. The Summit X450e-48p switch can be powered by one, two, or three external
power modules through the redundant power input connector on the rear of the switch.
The EPS-C (External Power Supply Chassis) is shipped with the redundant power supply cable that
connects to the redundant input connector on the rear of the switch. The EPS-C chassis can hold from
one to three 600-Watt EPS-600LS (external power module) units.
The PoE capability of the Summit X450e-48p switch varies depending on the number of external power
modules in use. Table 11
on the number of power supply modules in use.
